Good morning from germany,we have an awesome app already in the AppStore which is called HecFuel and our customers do use it. Because we have software for parking and refuelling we want to bring this app into Car Play to increase the user experience a lot.Does anyone know how to get this happened? I did contact Apple from the Developer Car Play Website but did not get any answer that helped me.Feel free to comment with anything that comes to your mind!Have a nice day, Thomas!

I did search on the internet, found some people who have the same problem but no one did get any solution yet... So I hope anyone here is the G I am searching for..1 - I did enable "Location updates" and "background fetch" in Background Modes.https://i.stack.imgur.com/eNW4K.png2 - I did call locationManager.startMonitoringSignificantLocationChanges() on the right place, I checked this on the way I write and string into my Firebase Database when the app will be waked up after terminating.3 - I am checking on the right way if there is a location key in launchOptions just like Apple on their documentation, see:https://developer.apple.com/documentation/uikit/app_and_environment/responding_to_the_launch_of_your_apphttps://i.stack.imgur.com/cW3dx.pngSo why is my launchOptions nil? I cannot understand why this happens... Because the App is getting waked up, the mistake cannot be on my locationManager handling..I found this on stackoverflow but my launchOptions are nil so the code is not getting inside the if...https://stackoverflow.com/questions/34527972/location-update-even-when-app-is-killed-terminatedPlease help.When my app launches the first time after installing, I initialize the locationManger. When I use the switchToogle for enable/disable location tracking, I start/stop the locationManger updating location.When my app goes in background, I restart the location updating.When my app was killed by user, the app wakes up and starts into app delegate method didFinishLaunchWithOptions.I hope its clear how my code works, if not just tell me!LocationMangerClass:import Foundationimport CoreLocationimport Firebaseclass LocationManagerClass : NSObject { static var locationManager: CLLocationManager! override init() { print("init...")
